INTEGRATED CIRCUIT HAVING A MEMORY WITH PROCESS-VOLTAGE-TEMPERATURE CONTROL

Certain embodiments of the inventions provide an integrated circuit (IC) having a processor operatively coupled to a PVT (process-voltage-temperature) source and an adjustable memory. The processor receives from the source an input characterizing the present PVT condition and generates a command for the memory based on that input. In response to the command, the memory adjusts its internal circuit structure, clock speed, and/or operating voltage(s) to optimize its performance for the present PVT condition. Advantageously, the ability to adjust the memory so that it can maintain its functionality and deliver an acceptable level of performance under unfavorable PVT conditions provides additional flexibility in choosing circuit design options, which can produce area savings and/or increase the yield of acceptable ICs during manufacture.
